Orbit Pendant Speaker

OPS1

Installation and Use Manual

Product Description

Thank you for choosing NEAR® Orbit Pendant Loudspeakers.You have purchased

one of the finest pendant loudspeakers available today, the NEAR Model OPS1.

Please familiarize yourself with this product by reading and reviewing the descrip-

tions and diagrams in this manual.

All NEAR products include similar technical and design aspects that are unique to

the market. NEAR invented and patented the "spiderless" woofer (MLS™), which

features a high-gauss ferrofluid to guide the voice coil through the magnetic field.The

benefits over conventional woofers with cloth spiders are several, including the

ability to constantly adjust voice coil alignment, extend linear excursion, and the

most efficient path for cooling the voice coil.

In addition, the use of metal-alloy cone structures provides several benefits over the

usual paper or plastic cone, such as elimination of cone flex or "break-up" in the

operating ranges, additional thermal path for the voice coil to stay cool, and an

extremely stable cone structure unaffected by changes in temperature.

The NEAR OPS1Pendant Loudspeaker is a full-range, wide dispersion system

providing overhead sound coverage where ceiling structures are high but the sound

needs to be closer to the audience/listener. An optional cable kit (CK10), suitable

for safety or main drop cable, is available.

Settings for both 70V and 100V high-impedance systems, as well as a low-impedance

(16-ohm) position, are provided.

The OPS1features a removable snap-lock input connector, providing easy wire

connection for input as well as loop-through to the next speaker.

IMPORTANT

The OPS1is not an outdoor speaker. Do not expose the speaker to rain or

moisture.The OPS1should be installed by qualified personnel.

Selecting Power Level

Select the power level using the front-mounted selector switch. The speaker grille

must be removed prior to selecting the power level. See Speaker Grille Installation &

Removal section for proper grille removal procedures.

Selecting Power Level

The front-mounted selector switch (under grille)

is used to set the appropriate power level or imped-

ance for your system. Using a small flat-blade screw-

driver, turn the knob until the slot points to the

power level you require.

70V/100V Systems

Both power setting scales for 70V and 100V systems

are labeled on the speakers. On the 100V scale, the

last position clockwise is marked with a (not avail-

able) symbol. Do not use this position in 100V

systems.

Systems

The fully counterclockwise position of the setting switch is the 16-ohm position.This

setting is suitable for use with low-impedance amplifiers that typically support 4- or

8-ohm speakers.The speaker’s higher, 16-ohm impedance makes it easier to combine

multiple speakers into series-parallel networks while keeping the total system

impedance at a level suitable for low-impedance amplifiers.

Speaker Grille Installation & Removal

Installation

The speaker grille fits tightly! Make sure the tap set-

tings are correct prior to re-installing grille. Push the

speaker grille in until it can go no further. Then, slap

around the edge of the grille to seat the grille. The

grille is properly seated when it is flush with the edge

of the bezel.

Removal

Insert a pocketknife blade between the grille and the

bezel about 1/4" deep and then gently pry the grille

upwards. Do this in multiple places around the

circumference of the grille to free the grille.

Speaker Wiring

Wiring is terminated at a snap-lock input

connector. There are two positive and two

negative terminals to accommodate daisy-

chaining of speakers in a system. All wiring

should be done prior to installation and then

plugged into the rear of the OPS1.

Daisy-Chaining

The OPS1’s snap-lock input connector allows

for easy daisy-chaining of speakers by providing

a second terminal of each polarity. Refer to the

figures for proper wiring for daisy-chaining of

terminals.

Speaker Phasing

Keep the same polarity terminals wired together to ensure correct phasing. In order

to provide the best possible sound, all of the speakers in a system need to be push-

ing out and pulling in at the same time.

If the connections to one speaker in a system are reversed from the others, that

speaker’s movement will be out of sync with the other speakers.This will result in a

loss of low frequency response and will effect the overall performance of the

system.

Speaker Installation

Suspension Cable Assembly

1. Screw the nuts onto the three (3) eyebolts all

the way to the flange.

2. Screw in eyebolts with captured cable

sections into the three (3) suspension points.

Do not overtighten.

3. Snap the loops of the three (3) free ends of

the cable sections into the quick-snap clip.

4. Connect the quick-snap clip to the drop cable

loop (not included).

Safety Cable (not included)

The speaker includes a safety cable suspension

point for extra protection. Refer to instructions

with cable kits for proper use.

Accessory

CK10 (Cable Kit, 10')

The CK10 is a 10-foot cable with one looped end, a forged eyebolt (with 1/4-20" x

1/2" thread), and an adjustable cable clamp. It is suitable for use as a drop cable or

safety cable.The CK10 is available in black, white, or silver.

IMPORTANT

The anchor point and any hardware used

to anchor the speaker must be able to

support the speaker’s weight under all

conditions. IF YOU ARE NOT SURE OF

THE PROPER CAPACITY OF THESE

ITEMS TO USE, CONSULT A STRUCTUR-

AL ENGINEER. Mount only one speaker

per supplied quick-snap clip.
